No probs, I thought I\'d read this before when I was making the decision to switch to RP so I thought I\'d have a look for it again.  It\'s an interesting read.

RP is fecking expensive, about £50 per 5 litres.  Price is a lot better bought in bulk - any chance the club could buy a large amount a sell it on to members at the per litre price?  208 litres works out at about £32.50 per 5 litres

Worth an ask I suppose

Why dont you organise a group buy then.
I will sell for a group buy at the drum rate.
I have 25ltr drums which means you only need 8 people or you need to find 41 people at 5ltrs, not so easy. I\'ll leave it up to you.

Its also not so dear as Ive said before when you concider the extended oil change periods, cooler runing, better fuel economy etc I think it works out cheap if looked properly.

A quote from Royal Purple.

"Many view lubricants as a commodity, where low price and service issues dominate purchasing decisions. Therefore, oil companies seeking large market share have a great incentive to keep manufacturing costs low and little incentive to dispel the myth and upgrade the quality of their lubricants".

The Focus

Royal Purple strives to produce lubricants that provide the highest level of performance available on the market today. Because Royal Purple\'s sole focus is to create state-of-the-art lubricants it develops products that significantly outperform in laboratory settings and more importantly, in the field.

The Myth

Many view lubricants as a commodity, where low price and service issues dominate purchasing decisions. Therefore, oil companies seeking large market share have a great incentive to keep manufacturing costs low and little incentive to dispel the myth and upgrade the quality of their lubricants.

Royal Purple, however, recognizes that lubricants are not commodities. Reliable equipment operation critically depends upon the quality of the lubricant used. Lubricant performance directly and significantly affects how long, how reliable, how efficient and at what cost (i.e. parts, labor, downtime, number of oil changes and energy costs) your equipment will operate. For instance, lubrication-related failures account for 54 percent of all bearing failures.

The key to Royal Purple\'s ability to outperform leading synthetic-based and mineral-based oils is Synerlec®, the cornerstone of Royal Purple\'s entire line of products. Synerlec® is Royal Purple\'s proprietary, lubricant additive technology that strengthens the oil film to provide extra protection and performance.

High Film Strength

By definition, film strength is a lubricant property that acts to prevent scuffing or scoring of metal parts. Film strength is measured by the American Society for Testing Materials\' (ASTM) Timken OK Load test, which measures the heaviest load that a lubricant will sustain without scoring the test block. Royal Purple\'s film strength is up to 400 percent stronger than other synthetics, which greatly reduces wear and extends equipment life.

Continuous Protection

Royal Purple continuously protects because Synerlec® continuously adheres to metal parts â€" even after shutdown. The thin film of oil that remains after shutdown preserves parts and provides instant lubrication at start-up until a full fluid oil film can be established.

Reduced Friction

The primary purpose of any lubricant is to reduce friction. Reductions in friction can substantially increase equipment performance and extend equipment life. As measured in the Falex No. 1 Friction Test, Royal Purple reduces friction up to 78.7 percent when compared against conventional lubricants.
 
Reduced Vibration

The severity of bearing vibrations is directly related to the condition of the bearing and the quality of lubrication. Royal Purple significantly reduces bearing vibrations, noise and temperatures. In the following example of a 200 hp roots blower, Royal Purple reduces vibrations by approximately 95 percent in only three days.  

Reducing vibrations extends equipment life in proportion to the reduction in vibrations as shown in this table. For example, according to Reliability magazine, reducing vibrations by 50 percent increases ball bearing life by 700 percent and other rolling element bearings by 908 percent.

Micro-polishes surface irregularities

Royal Purple micro-polishes asperities (irregularities on bearing surfaces that prevent the lubricant from fully separating components) to further reduce friction.

     
A new bearing surface appears smooth until magnified 1500X   The same bearing surface roughened after using a leading synthetic oil.   The same bearing surface after being micro-polished by Royal Purple.

Notice that after using Royal Purple® the bearing surface is now significantly smoother than it originally was. Smoother surfaces reduce friction.

Superior Water Separation

Many oils emulsify with water, which shortens the life of both the oil and the equipment it lubricates. Royal Purple rapidly separates from water, allowing for easy removal of water from the bottom of the oil reservoir.

Reducing the water content in oil from 500 ppm to 45 ppm increases the machine life by 400 percent.

Corrosion / Rust Protection

Royal Purple provides outstanding corrosion and rust protection to ferrous and nonferrous metals. It excels in the ASTM\'s Copper Corrosion test and Cincinnati Milacron test and continually protects as a result of its ability to constantly adhere to metal surfaces.

Longer Oil Life

Many lubricants have a short service life because they lack oxidation stability. Oxidation causes increased viscosity and oxidized oil deposits. A product\'s ability to resist oxidation is measured by the ASTM\'s Turbine Oil Stability Test (TOST) and Dry Air Oxidation test and the ASTM’s Thin Film Oxidation Uptake Test (TFOUT). Royal Purple not only surpasses leading mineral-based and synthetic-based oils in these tests but also outlasts the duration of the TFOUT test. Royal Purple\'s superior oxidation stability and its ability to clean deposits left by previous oils results in fewer oil changes, saving time, money and the environment.

Cleaner

Royal Purple\'s best-selling industrial lubricants are filtered to a level 150 to 200 times cleaner than conventional lubricants. Cleaner lubricants reduce wear to extend engine and equipment life.

Improving the ISO 4406:99 cleanliness level of a hydraulic oil from 20 / 17 to 13 / 11 will increase the hydraulic system life by 6 (600 percent). Royal Purple is typically filtered to a cleanliness level of 14 / 13 / 11.

Royal Purple\'s lubricants are packaged in new, clean poly drums, pails and bottles to ensure that product cleanliness is maintained from blend to delivery. Couple this with Royal Purple\'s state-of-the-art precision blends, and you\'ll always receive the same, dependable product each and every time.

Switching to Royal Purple will produce meaningful immediate and long-term results. Royal Purple delivers significantly improved equipment reliability and uptime, plus reductions in energy and maintenance costs. While actual savings will vary from plant to plant, many companies have documented millions of dollars in savings per year after converting to Royal Purple\'s lubricants.

Energy and maintenance savings typically cover the cost of the oil within a few months, turning what was once an expense into a profit. In refrigeration compressors alone, Royal Purple produced an average energy savings of 10.11 percent. [Read the Machinery Lubrication article documenting the independent tests.] Even the smallest reductions in energy savings can drastically leverage savings. The following chart, taken from the Machinery Lubrication article, illustrates this point.

A pdf to read

I would love to know for definite if any present day synthetics can break "tip to chamber wall" contact and therefore reduce or destroy compression.QUOTE]

Would not have thought a film of oil, how many micron? Would destroy compression? But may lower compression.
Lowering compression may not be a bad thing, if it saves fuel, engine etc but still runs with a slightly lower compression, that can’t be bad.
Using ceramic tips (you have used them) has proven to lower compression but are still a good thing, and still being used.
So not sure why this would be a deciding factor.

I\'m a bit confused by this bit! not sure i want to risk lowering compression!and not sure how that would save fuel,or be a good thing in any way, i don\'t care about the fuel (not much, ) it\'s the oil effeciency i am interested in and protection for my Apex seals and housings,
Clive are you saying that mineral oils can also break "tip to chamber wall" contact and therefore reduce or destroy compression? or that mineral oils do not have that effect?
All interesting stuff this, all new to me!

Royal Purple 10w40 has a HTHS of 4.05 cant find NOACK
I have asked RP for these, I\'ll wait and see.
HTHS is mentioned on the pdf from there site.

I said in a very early post on here which Clive removed.

"Like prefered tuners, ones not always better than another, poeple have prefered oils, this will influence what they buy.

Some will stick there heads in the sand and because Mazda used information thats now 25 years old, will say "if it\'s not broke don\'t fix it".

How many guys with RX7\'s will be here in 2 years time, with the constant turnover of cars being sold, those may just say nutts, cheap will do, I wont have it come engine build".

It would be a good idea for a list providing people dont too hung up on whats best, sometimes there is little point putting a RP race oil because its better than RP 10w40 beacuse the car is not used in such a way that it will benefit from it. Same Im sure applies to Silkolene, some of there grade oils far outstrip the quality needed for some cars.

MRC does have to be carefull, Clive is also a vendor who sells 76 Oils, so to a degree has a vested interest in members buying mineral or 76, and has recommended that people who want to save money go to Asda and buy it. I know I wont put oil in my car that I can buy for £2.75 a drum. So cant see that in the clubs interest to recommend.

If a list has to be made, and MRC have to get involved, why not just put a list of oils that MAYBE (cause you will never prove it) wont harm, because it will be a hard job to list and state reasons why.
If MRC keeps out of recommending then it will be down to the vendors to recommend and face the outcome. If Clive wants to act as a vendor and put forward 76 Oils tech in a SHY thread thats cool, each can state there qualities, and let members decide but not to say the club recommends, as its not the club, its the club president and vendor telling all to use mineral.

So what if the HTHS number is .05 better, it will still be good enough.
Sometimes there is too much confusing information.
Its good to read techy posts, and Simon has a wealth of knowledge, cant take away,

I enjoy Simons threads. Just trying to put a balance on it, as Im none technical.

If any of this upsets Simon then please remove, posted as a couple kinda asked about RP. Im not getting in to my oils better than yours.

Hi Bob, I was trying to say that Clives question about tip to chamber wall was not really relivent, as ceramic seals dont give as good a seal as steel but still work well, hence me saying loss of compression (very small) was not necissarily bad. I did not believe that a 3 micron gap because of a layer of film from oil would make you loose compression. On Simons thread a expert chemist has disproved it as well, even though a valid question for someone to ask about tips and sealing.
Simons Silkolene chemist
Quote
"Regarding seal tip to chamber wall’ contact, the fact that people feel that there must be actual contact shows that they don’t know what is really happening! It’s no different from piston ring action in normal 4-stroke engines. Except at the top and bottom of the cylinder bore, where the ring is stationary for an instant, the velocity of the ring generates a ‘wedge’ of oil which floats the ring off the bore surface by a few thousandths of a millimetre, preventing metal to metal contact, and reducing wear to virtually zero. (Hydrodynamic lubrication.) That’s why modern 4-stroke motors last so long! In fact, the oil helps the ring to hold compression and prevent blow-by.

In a rotary, if a perfect oil film could be maintained on the chamber walls, seal and chamber wall wear would be negligible and compression actually improved, giving better efficiency and long component life up to or even better than 4-stroke piston standards*. Unfortunately, the severe conditions in a rotary with most of the chamber walls being exposed to hot gas means that this ideal situation never exists, but a top quality synthetic lubricant with superior temperature resistance goes a long way towards achieving this ideal".

I have spoken with one of the chemist at Royal Purple, David, the guy who has a vast knowledge of racing rotaries.
He has confirmed my thoughts, not to get involved with the usual my oils better than your oil, with chemists posting all sorts of test figures, that to the average guy means nothing, and are usually only relivent to research most of the time.
He has given me a couple of items to post, independent from various bodies for those interested.
Although a good research lab, like many politicians can make the figures go in there favour, there is, apart from the fact that most of the good/true fully syn oils will be better for your rotary than minerals, to let the oils speak for themselves.
8 out of 10 forumula 3 teams did not BUY Royal Purple for no good reason, when the big companies give there oils away to race teams as they can afford to and simply get a name on a car.
Royal Purple was chosen on its performance.
It would be interesting to see the same car on the same day with the same rollers, do an oil performance test. Then you would possibly see the difference in the top oils.
